pendulum
Pendulum is one apparatus which is weightless, stiff bar that experiences no friction, and can swing freely. Pendulum can move to and fro from its equilibrium position, depending on restoring the force due to the gravity and can...

Security is a big challenge everywhere because thefts are increasing day by day owing to the unsafe and insecure security systems in homes, commercial complexes and industries. Several conventional technologies are available to keep home...

Register is a main part in the microcontrollers and processors that provide a fast way to collect and store data. If we want to manipulate data with a controller or processor by performing addition, subtraction, and so on, we cannot do...

Quiz buzzer systems are mostly used in schools, colleges and also in live quiz competitions broadcasted via television. A Quiz buzzer allows any user to press the switch quickly in response to a question posed during competitions that are...

Many of the microcontroller applications require counting of external events such as frequency of the pulse trains and generation of precise internal time delays between computer actions. Both these tasks can be implemented by software...

Over the years, project development has advanced over leaps and bounds. Of course, it’s good to keep up with the times, but in some situations, radical changes might not be so beneficial. We’re here to talk about the staple microcontroller,...

The most powerful and important features are interrupts in 8051 microcontroller. In most of the real-time processes, to handle certain conditions properly, the actual task must be halt for some time – it takes required action – and...

Interfacing is one of the important concepts in microcontroller 8051 because the microcontroller is a CPU that can perform some operation on a data and gives the output. However to perform the operation we need an input device to enter...

What is a Matrix Keypad?
A keypad is the most widely used devices of digital circuits, microcontrollers or telephone circuits. Many applications require large number of keys connected to a computing system. Provided that it for the most...

Embedded Systems Projects is possibly the principal solitary group of projects, particularly with regard to electronics & electric students. These embedded projects are also the most admired group amid the electronics & electric...
